Transmit Modulation Mode
The modulation mode currently being used on the transmit channel. The number in brackets
after the modulation mode and coding rate string is the effective data rate available to all MAC
layer protocols. List of all the modulation modes can be found in Section 12 "Data Rate
Calculations" ,where data rate calculations plots are given for each available modulation
mode.
Receive Modulation Mode
The modulation mode currently being used on the receive channel. The number in brackets
after the modulation mode and coding rate string is the effective data rate available to all MAC
layer protocols. List of all the modulation modes can be found in Section 12 "Data Rate
Calculations", where data rate calculations plots are given for each available modulation
mode.
Receive Modulation Mode Detail
This supplies the user with information regarding the receive modulation mode in use.
Possible values are:
"Running at maximum receive mode"
"Running at user-configured Target Modulation Mode"
"Restricted because Installation is armed"
"Restricted because of byte errors on the wireless link"
"Restricted because a DFS channel change is in progress"
"Restricted due to the low Ethernet link speed"
"Limited by the radio conditions"
Signal Strength Ratio
The Signal Strength Ratio is the ratio of the power received by the Vertical / Horizontal
receivers and presented as: max, mean, min, and latest in an histogram format. The max, min
and latest are true instantaneous measurements; the mean is the mean of a set of one
second means. See Section 7.3.1 "Histogram Data".
Wireless Link Availability
Expresses the link availability as a percentage of time since the first successful registration
after a system restart, expressed as a percentage to four decimal places.
Byte Error Ratio
The ratio of detected Byte errors to the total number of bytes since the last system reboot.
This is a true measure of link quality as this measurement is made continually using null
frames when there is no user data to transport.
Code Word Error Ratio
The ratio of uncorrected Codeword errors to the total number of Codewords, calculated since
the last reset of the system counters.
Statistics Page Refresh Period
The statistics page refreshes automatically according to the setting entered here (in seconds).
Reset System Counters
By pressing this button all counters in the system are reset to zero.
Reset System Histograms
All histograms are reset, and the calculation period is restarted.
